Rocky Mountain Thunderbolt Carbon 90 BC Edition 27.5" Mountain Bike 2018 - Trail Full Suspension MTB
Rocky Mountain has created a beast, taking the long established hard-charging Thunderbolt trail bike and beefing up the wheel travel and spec into a more gravity friendly version with this BC edition.
Keeping small bump sensitivity and mid-stroke support rear wheel travel has increased from 120mm to 140mm along with the front. Longer reach, slacker head angle and lower bottom bracket see this trail bike blur the line with enduro.

SRAM Eagle and, Stans rims and Maxxis minion tyres solidify this bike as a versatile and contemporary trail bike.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
